Foxpro hanging on Windows XP

Question

Foxpro 2.6a has been running fine on my Windows XP machine, but suddenly just hangs at the first information screen when I click the icon to start. When I try shutting it down with the Task Manager, it says the program is not responding then ultimately tell me that NTVDM.EXE is not responding. Help! How do I get Foxpro 2.6a to run again?

Well - the problem is now solved. Turns out that it was the sprtcmd.exe task that was causing Foxpro to freeze. When that was stopped, Foxpro opens and runs fine. The only clue was that about the time that Foxpro started freezing, I'd get a message when shutting down the computer that the sprtcmd.exe was not responding and I would have to click End Now.

Check to see if its a dual core machine or anything with 2 processors.The easy, temporary fix is to open up task manager while fox is running and then right click on the ntvdm task. If you have the option 'set afinity' then click on that and remove any processors except processor 0. If that fixes the problem, then you have to patch ntvdm so its permanently uses a single processor. To do that, lookup other similar posts in this group or use google.

Thanks for responding. I tried right clicking on the ntvdm task in the task manager and the only options that came up were End Process, End Process Tree and Set Priority. The Set Priority was at Normal. I didn't see anything about the 'set afinity'. I don't know if I have a dual core machine.

When I tried to end the Foxpro task and it gave me the NTVDM.exe not responding, it then came up with a System Error that said "The request to end the selected 16 bit task has timed out. The win 16 subsystem may be unstable." Does that help?

"shutting down the computer that the sprtcmd.exe was not responding and I would have to click End Now"

I get this error ANYTIME I shut down my PC. I don't know why all of the sudden in the last month this has been happening. If I log off a profile to log onto another or just shut down the PC all together I get the error message "sprtcmd.exe was not responding " and I have to wait for it to go thru a ending process and then I click end now. Any ideas why this is happening???
